Really nice. If he wants to spend more time on this, additional hacks would be:

- hook up the foot pedal to a KVM or some kind of software switch to switch desktops/environments

- put some speakers behind the 2 grills if it isn't done already

- make one or both of the grills openable and attach a power strip in them so the power wires can be hooked up hidden inside instead of outside

- cut out the flat part of keyboard cover and use it to extend the desktop for more desktop space and more leg room
